That way of naming a global function is essentially a poor
man's^W^Wexcuse me, I mean, C's way of working around the lack
of a proper namespacing / module system. In D, we do have a
proper module system, so you could just call the function
`drawLine` and put it in a file named Algo.d, then you can just
use D's symbol resolution rules to disambiguate between
Algo.drawLine and PersonalSpace.drawLine, for example. :-P

Again, stuffing it into a module is not the same thing as a
namespace. The user can just bypass this by writing `drawLine`,
there's nothing in the language currently that would 'force' the
user to write in a namespace-like/static-class-like fashion, and
that's the biggest problem.
